HalfNES v0.027 Changelog:

Since I'm trapped at home in a snowstorm with nothing else to do, might as well release. -Modified MMC3 scanline counter, which fixed Super Mario 3 and Silver Surfer -Made the APU counter count 4x a frame instead of 5 (off by one error) which makes music in a lot of older games sound closer to how it should be.
